Help with niche

I’ve had my health coaching business for 5 years and have managed to take it this far without narrowing my niche. Now that I want to do more online marketing (as opposed to in-person free talks), I recognize the need and importance of getting more specific and I am struggling with this!
Here’s what I have so far.
Holistic health-minded Women who are into yoga, age 40-55, who struggle with putting themselves first and have low energy, unwanted weight, anxiety and sleep problems.
They know what to do but they can’t seem to find the motivation and consistency to do it.
They are looking for a holistic approach and an answer to the question: Why do I make bad choices? Why do I do things when I know better?
They know what to do but they’re not doing it and are frustrated and lack self-confidence and self-worth.
They want to stop the cycle of self-sabotage and negative thinking so they can confidently be the healthiest, happiest version of themselves.
